  3. Motor PW GM4 ENET AI AI Zeolite production system 4. Main functions 1. Introduction 1) Various measuring data detection (analog input: 4~20mA) - temperature/pressure/flow rate/tank level/weight 2) Valve control - on/off valve (digital output) - analog valve (analog output: 4~20mA) 3) System integration and HMI monitoring using Ethernet. - monitoring (PLC -> HMI): Temperature, pressure, flow rate, weight, level, etc. - control (HMI -> PLC): Valve On/Off, analog value setting, PID setup value change 4) Measuring data sharing between PLCs and Interlock control using Fnet 5) Inverter (IS5) frequency control using Fnet 6) Drier control using PID function (2nd filtration & drying) - setup value (SV) = Temperature in the drier - when the temperature is low -> Increase liquid input volume - when the temperature is high -> Decrease liquid input volume - Process control and total monitoring system for Zeolite production process 1) Installation: 2002/02 2) Field: PA (water treatment) 3) Type: GM4 (DI/DO, AI/AO, Enet, Fnet), IS5, IH5, CIMON 4) Others 2.

Main functions 1. Introduction - Remote monitoring system for shipyard sewage treatment status using Ethernet 1) Installation: 2002/03 2) Field: PA (water treatment) 3) Type: GM4, Enet 4) HMI: Fix 1) Tank level monitoring - 4-step level detection (High-High, High, Low, Low-Low) by digital input from level sensors (4 points) and monitoring by HMI with Ethernet 2) Pump status monitoring - pump status (run/stop/fault) detection by digital input and monitoring by HMI with Ethernet 3) Ethernet communication - among GM4 PLCs in the same Subnet: High-speed link service - between GM4 (Master) and GM4 (each Subnet): FB (Function Block) service - between HMI and GM4 (Master): dedicated protocol service 2. System configuration GM4 CPU E NET DI (32*5) FB communication (20 Word) GM4 CPU E NET DI (32*5) dedicated communication (240 Word) Master PLC High-speed link (5 Word/station) GM4 CPU E NET DI (32*5) GM4 CPU E NET DI (32*5) Tank level & pump status Same Subnet 4. Others 1) FB communication is used because the subnet between PLCs is divided by media change (UTP/optical) and various routing equipment application such as switching HUB. 2) Master PLC collects data and HMI communicates with Master PLC. 4/22

  5. CPU PID DI DI DO DI AI AO Cement chlorine gas control system 3. Main functions 1. Introduction - PID control applied to chlorine gas control facility in kiln bypass system 1) Installation: 2002/1 2) Field: PA (cement) 3) Type: GM3 (AI/AO/PID/CNET) 1) Temperature control by setup temperature to control inverter RPM at each process step 2) Temperature is sent to the analog input module through temperature transducer 3) PID output is transferred to INV through the analog output module (4-20mA) for RPM control. 4) P value should be set below 1 for PID control because temperature changes abruptly 5) Temperature decreases as steam is emitted 6) GM3 Monitoring through Cnet module 2.
